Hi everybody,
I'm trying to comunicate with my SIM, which supports SIM application tookit, using the RIL API.
In order to do that I think I need:
- Send Command to the SIM (Envelope)
- Receive Response from the SIM (Fetch)
- Send Command Response to the SIM (Terminal Response)
At this moment I can do only the first two things.
I can send command using RIL_SendSimToolkitEnvelopeCmd function and using, as input, a well formed string as defined in the specification GSM 11.14; for example, in order to select the second item of the SIM Application Menu, I use this code:
BYTE envcmd[9];
envcmd[0] = 0xd3; // Menu selection tag
envcmd[1] = 0x07; // Length
envcmd[2] = 0x02; // Device Identity Tag
envcmd[3] = 0x02; // Device Identity length
envcmd[4] = 0x82; // Source: ME
envcmd[5] = 0x81; // Destination: SIM
envcmd[6] = 0x10; // Item Identifier tag
envcmd[7] = 0x01; // Item Identifier length
envcmd[8] = 0x02; // Item chosen
hres = RIL_SendSimToolkitEnvelopeCmd(m_hRil, envcmd, 9);
The response for this command is trapped in the notify handler (second thing I can do).
After the notification I need to send a Command Response to the SIM and to do that I think I need to use RIL_SendSimToolkitCmdResponse using, as input parameter, a well formed string as specified in the GSM 11.14; something like this:
// Response for DISPLAY TEXT
response[0x00] = 0x81;
response[0x01] = 0x03;
response[0x02] = 0x01;
response[0x03] = 0x21;
response[0x04] = 0x81;
response[0x05] = 0x02;
response[0x06] = 0x02;
response[0x07] = 0x82;
response[0x08] = 0x81;
response[0x09] = 0x03;
response[0x0a] = 0x01;
response[0x0b] = 0x00;
hres = RIL_SendSimToolkitCmdResponse(m_hRil, response, 12);
But the result (hres) is always 0x80070057 (E_INVALIDARG).
Could anyone help me?
Thanks in advance.

P.S.: please note that the response I send is the same as that I sniffed using a Season logger which can intercept all traffic between SIM and PDA.
Although I can't help, I've got a question: Once you're finished - could this then be used to implement Bluetooth SIM Access Profile?
No.
In order to implement SAP, we need a "flat" access to the SIM and to do that the radio module has to export a commad like AT+CSIM (GSM 07.07).
If the radio module implements that command, using the RIL_SendSimCmd we can send all possible commands to the SIM and so we could develope a SAP layer.
Unfortunally, as I know, there is no radio module that permits a complete access to the SIM.
Before to take the SAT street I tryed to use SendSimCmd on my JasJar but the reult was always E_NOTIMPL.

SendSimCmd is implemented on the Wizard, at least (I'm using it ) - but it'll only be useful if you want to access a specific application on the card (if you're trying to talk to the GSM application on channel 0 you're out of luck)
Regarding SendSimToolkitEnvelopeCmd I've got mixed results according to the devices - working on some, and failing on others with this return code, and do not know why, yet. But here since you're failling on the SendSimToolkitCmdResponse, that seems different. Even if I never used this function before (I always let the handset provide its own Terminal Reponse) I think it's badly formatted. The response to a Display Text should only include a General Result (0x03 0x01 0x00).
What do you mean when you say "...to access a specific application on the card"?
What kind of PDU are you able to send to the SIM? And how can you specify which channel you want to open?
BTW, in order to implement SAP, we need to access to channel 0 for sending GSM commands.
Regarding RIL_SendSimToolkitCmdResponse, I tryed also to send General Result (0x03 0x01 0x00), as you suggested, but with no luck.
I think SendSimToolkitCmdResponse wants a specific struct as input parameter (something like specified in this document http://www.intrinsyc.com/whitepapers/RIL_whitepaper_MS_Intrinsyc_June2004.pdf).
I tryed with the struct specified in that document and the resut is changed: 0x8007000e (E_OUTOFMEMORY) :-(
Any ideas?
I have a JasJar with WM 5.0.

Basically you'll need to open a channel to your application with an ISO 7816-4 Open Channel command, then you are in your own world

OK, then it's going to be difficult I think. Unless you have a 3G card and a multi-selectable USIM application that you could select on another channel to send your APDUs, but I don't know if this is supported by any card (never tested it).

I did a small project some years ago that can be used to install a dummy driver that'll record everything. I think you can use it for RIL and try to dump the structure that's sent to understand it better (and publish the results here )
http://arisme.free.fr/hacks/binaries/XBridge.zip
Arisme, your application is very cool
With your driver I can see all traffic between RIL.dll and rilgsm.dll and so I can see the commands sent by STK_Service.dll (SIM Application Toolkit layer in the JasJar) to the rilgsm.dll via ril.dll.
The structure used by the RIL.dll to communicate with rilgsm.dll in the function RIL_SendSimToolkitCmdResponse is:
typedef struct rilsimtoolkitrsp_tag
{
DWORD cbSize; // Structure and text size in bytes
DWORD dwParams; // Indicates valid parameters
DWORD dwId; // ID number of command
DWORD dwTag; // Command tag (with comprehension bit)
DWORD dwType; // Type of command (DISPLAY TEXT, etc.)
DWORD dwQualifier; // Command details qualifier
DWORD dwResponse; // Command result from SIM toolkit layer
DWORD dwAdditionalInfo; // Additional command result information.
} RILSIMTOOLKITRSP;
as defined in the document linked in my previous post.
I used the same structure as parameter for RIL_SendSimToolkitCmdResponse, but the question is: is it correct?
That structure is used between RIL.dll and rilgsm.dll and not between my application and RIL.dll.
BTW I tryed to fill the fields with the info logged with your driver and the result is always the same: 0x8007000e (E_OUTOFMEMORY).
I think I need to intercept the call that STK_Service.dll makes to RIL.dll.
Now I'll try to bypass RIL.dll using RIL1: device and DeviceIoControl.
Bye
Sektor
Did you check if the info passed in the IOControl associated to this RIL function (you'll have to find which one it is first ) logged by the bridge matches this structure ?
Yes, I did and the structure matches the info logged.
But I am not sure that the same structure can be used from my application.
When I use that structure as parameter for RIL_SendSimToolkitCmdResponse the response is always bad, as I said.
But I have good news: using RIL1: device and DeviceIoControl I can send a command response; here the code.
#define RIL_SEND_STK_ENVELOPE_RESPONSE 0x300018CL
RILSIMTOOLKITRSP rsp;
memset(&rsp, sizeof(RILSIMTOOLKITRSP), 0);
rsp.cbSize = 0x20;
rsp.dwParams = 0x1f;
rsp.dwId = 0x01;
rsp.dwTag = 0x81;
rsp.dwType = 0x21;
rsp.dwQualifier = 0x81;
rsp.dwResponse = 0x00;
rsp.dwAdditionalInfo = 0x00;
BYTE *b = (BYTE *)&rsp;
int s = rsp.cbSize;
DWORD rildevresult = 0;
DWORD nReturned = 0;
HANDLE m_hRilDev= CreateFile(L"RIL1:", GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, 0, OPEN_EXISTING, FILE_ATTRIBUTE_SYSTEM, 0);
if (!DeviceIoControl(m_hRilDev, RIL_SEND_STK_ENVELOPE_RESPONSE, b, s, &rildevresult, sizeof(rildevresult), &nReturned,0))
{
rildevresult = GetLastError();
debug("Error: %08lx\n", rildevresult);
}
debug("DeviceIoControl(RIL_SEND_STK_ENVELOPE_RESPONSE): %08lx\n", rildevresult);
BTW I prefer to find the correct structure for RIL_SendSimToolkitCmdResponse.
Bye.
Sektor
that's a good step forward already 8)
I found the solution
The function prototype in the ril.h is NOT correct!
In ril.h RIL_SendSimToolkitCmdResponse is defined as:
HRESULT RIL_SendSimToolkitCmdResponse(HRIL hRil,const BYTE* lpbResponse, DWORD dwSize);
The correct definition for my ril.dll is:
HRESULT RIL_SendSimToolkitCmdResponse(HRIL hRil, const RILSIMTOOLKITRSP* pRsp, const LPBYTE pDetails, DWORD dwDetailsSize);
where RILSIMTOOLKITRSP is
typedef struct rilsimtoolkitrsp_tag
{
DWORD cbSize; // Structure and text size in bytes
DWORD dwParams; // Indicates valid parameters
DWORD dwId; // ID number of command
DWORD dwTag; // Command tag (with comprehension bit)
DWORD dwType; // Type of command (DISPLAY TEXT, etc.)
DWORD dwQualifier; // Command details qualifier
DWORD dwResponse; // Command result from SIM toolkit layer
DWORD dwAdditionalInfo; // Additional command result information.
} RILSIMTOOLKITRSP;
and pDetails is a buffer with the data needed to complete the response, e.g.:
BYTE details[3];
details[0] = 0x90;
details[1] = 0x01;
details[2] = 0x0b;
in order to select the item "0x0b" in response to a "select item" proactive command, or
BYTE details[14];
details[0] = 0x8d;
details[1] = 0x0c;
details[2] = 0x04;
details[3] = 0x74;
details[4] = 0x65;
details[5] = 0x6c;
details[6] = 0x65;
details[7] = 0x76;
details[8] = 0x69;
details[9] = 0x73;
details[10] = 0x69;
details[11] = 0x6f;
details[12] = 0x6e;
details[13] = 0x65;
in order to give an input data ("televisione" in this example) in response to a "get input" proactive command.
I don't know if the parameters for that function depend on the ril version, however I give you the details about my device:
I-Mate JasJar
ROM: 1.13.46 ITA (09/23/05)
Radio: 1.03.01
Protocol: 42.36.P8
ExtRom: 1.13.126 ITA

Thanks, good to know 8)
Many thanks for this topic, it was my guide to RIL_STK programming. I've spent some time developing automatic Multi-SIM switcher application, and would like to share some information (ohh, I'm ETEN M600 owner, so this info could be wrong for other devices).
1. In my case RIL_SendSimToolkitCmdResponse takes DWORD details data, not the BYTE one Sector described in previous post. Information it should contain also differs, it looks like regular RIL structure, not like the GSM standart described Terminal Response. Example of SelectItem response data:
DWORD details[3];
details[0] = sizeof(details);
details[1] = 0x01;
details[2] = selectedItem;
2. The only documentation about RIL structures I had was the Sector links to some PDF's describing RILSIMTOOLKITRSP and RILSIMTOOLKITCMD. I needed however to decode incoming notifications, so I've reversed structures coming from SIM in SelectItem case (lpData points to RILSIMTOOLKITCMD, +dwDetailsOffset you get RILSIMTOOLKITSELECTITEM, +dwOffsetAlpha = menu caption, at +dwOffsetItems you could get dwNumItems looking like RILSIMTOOLKITITEMDESC:
typedef struct rilsimtoolkitselectitem_tag
{
DWORD cbSize;
DWORD dwNull0;
DWORD dwNull1;
DWORD dwNull2;
DWORD dwSizeAlpha;
DWORD dwOffsetAlpha;
DWORD dwNumItems;
DWORD dwSizeItems;
DWORD dwOffsetItems;
} RILSIMTOOLKITSELECTITEM;
typedef struct rilsimtoolkititemdesc_tag
{
DWORD cbSize;
DWORD dwNull0;
DWORD dwItemID;
DWORD dwNull1;
DWORD dwNull2;
DWORD dwSizeAlpha;
DWORD dwOffsetAlpha;
} RILSIMTOOLKITITEMDESC;
3. In overal it seems RIL of my M600 encodes all commands and notifications to such structures and requires similar structures for STK commands, altrough that is not obvious while reading this topic and available documentation.
wbr, Nik.
P.S. ETEN M600, fw 216.
P.P.S. Sorry for interferring with not HTC-clone device, just couldn't found another such usefull WM developers forum.
Hi,
I'm a newbie to the RIL API.
So, first of all, thx to all of you for giving me good info on this in your discussions.
I'm having no success with the RIL_SendSimToolkitEnvelopeCmd function.
Just for testing, I'm sending the same test command as above:
BYTE envcmd[9];
envcmd[0] = 0xd3; // Menu selection tag
envcmd[1] = 0x07; // Length
envcmd[2] = 0x02; // Device Identity Tag
envcmd[3] = 0x02; // Device Identity length
envcmd[4] = 0x82; // Source: ME
envcmd[5] = 0x81; // Destination: SIM
envcmd[6] = 0x10; // Item Identifier tag
envcmd[7] = 0x01; // Item Identifier length
envcmd[8] = 0x02; // Item chosen
hres = RIL_SendSimToolkitEnvelopeCmd(m_hRil, envcmd, 9);
In the result callback, I'm getting dwCode == RIL_RESULT_ERROR and lpData points to E_FAIL (0x80004005).
Now, I've enabled logging and my celog shows that the RIL driver is getting the folowing command.
0:02:47.449.538 : DEBUGMSG: PID:0x805d8dc0 TID:0x834a576c [RETAIL]RilDrv: Sending cmd: AT+SATE=0,D30702028281100102
The response is also shown as:
0:02:47.484.606 : DEBUGMSG: PID:0x805d8dc0 TID:0x8349d974 [RETAIL]RilDrv: Accumulated response: +SATE: 0F00006F008169B4ECAA19CDF41D6A35C8<cr><lf>
I was expecting to recieve the response "6F00" in the result callback.
Any ideas?
If you can give me any other command to test the envelope command, that would help.
Thanks,
-R.

Hi:
I've been researching in XDA forums with no success so far. A few days ago I found this thread that you participated in a long time ago. Actually, my problem is I don't know how to access in Windows Mobile an applet application located by means of its AID... I've tried to send selection command:
Code:
00 A4 04 04 10 D2760001180002FF34004F8908010D09
thorugh RIL_SendSimCmd, but it didn't work (response=0x01 0x05 0x00 0x81).
Would you, please, give me a hand? I'm absolutely lost and desperated.
Thanks in advance...
I found the solution:
We must use logic channels. 0 Channel is reserved for GSM/USIM, other channel, usually #1, is used for applets.
APDU's sequence is:
Manage Channel (Open)
00 70 00 00 01
Respose
0x 90 00 (Where "x" indicates the logic channel assigned by the smartcard. Usually the respose is "01 90 00", being "01" channel number one).
Select Local APP
0x A4 04 04 10 <AID> (Substitute "x" for channel number assigned in Manage Channel (Open) command response ("1" in the case of our example).
Response
90 00
COMMAND INVOCATION
From now on if we want to send commands to the app, we just have to indicate the channel in CLASS byte (i.e. "9x" being "x=1", hence 91[INS][...])
Manage Channel (Close)
00 70 80 0x 00, where "0x" indicates the channel number we want to close. ("1" in our example).
Thanks anyway...
Hello all! I'm somewhat new to Android development, I'm using eclipse to do all of my development. Right now I am working on an "away message text" application. I am having trouble with database query returning a string of the first index of data. Here is my code where i am trying to pull data from the database. This is being done inside my ReceiveText class, which extends BroadcastReceiver.
mDbHelper = new TextsDbAdapter(context);
mDbHelper.open();
getText = mDbHelper.fetchText(0);
message = getText.getString(getText.getColumnIndex(mDbHelper.KEY_BODY)).toString();
The error that I am getting is Cursor index out of bounds...any recommendations? Thanks!
you always start out of bounds.... you have to moveToFirst() first...
Thanks. Would I moveToFirst() before I fetchText()?
you're probably going to have to change how the fetchText method is implemented.
you'll probably want something like
Code:
public String fetchText(int id){
Cursor c = getContentResolver().query( uri,
new String[] { <name_of_text_column> } ,
"_id == " + id, null, null);
String text = null;
if( c != null ){
if( c.moveToFirst() ){
text = c.getString( c.getColumnIndex( <name_of_text_column> ) );
}
c.close();
}
return text;
}
Thanks. The method I have for fetchText returns a Cursor, however I made another method that returns a string, similar to what you recommended. For some reason, there is something wrong with the rowid sending in, I want to just get the first one, if I'm not mistaken, wouldn't it be 0? I have a seperate ReceiveText.java class, which extends Broadcast Receiver. The part where the messages are stored into the database is very similar to androids notepad demo. When a text is received, I want the ReceiveText class to query the database and just pull the first text that was actually stored into the database. I have 3 columns, KEY_ROWID, KEY_TITLE, and KEY_BODY. For some reason there is an issue when trying to query the database from the ReceiveText class. Any ideas that would make better sense or be easier to implement? Any help is much appreciated.
oh, right. I wasn't paying attention and for some reason I thought it was returning a string. I see now that it's obviously a cursor..
what you are doing sounds fine but you sure really look at the database on the phone/emulator.
open up adb and type
Code:
sqlite3 /data/data/<name_of_app>/databases/<name_of_db>
then you can do
Code:
select * from <name_of_table>
personally, I find it way easier to read if you change the mode with a ".mode line" command(the dot is important).
that should give you a good idea of why it is not working properly.
How do I open up the adb? I looked online, and it says i can run it through command line, or terminal since I use ubuntu, but I'm not sure exactly how to open it. Apologies for my noobness with android development i'm trying to learn!
if you're running it on a phone/tablet, you'll have to set up the adb drivers
but if you're just using the emulator, you're fine
Code:
cd /<path_to_sdk>/platform-tools/
./adb devices ##this should list the device. if not you have a problem.
./adb shell
and now you can execute commands on the device, like sqlite3
Awesome, I got that to work, and i can see the three "texts" that i've added to the database...looks like this...
1|Sleeping|Sleeping...text you when I wake up.
2|Driving|Driving right now...text you when I'm done.
3|Xbox|Playing xbox...text you later.
So this means that my database works. The numbers 1,2, and 3 are the KEY_ROWID, sleeping, driving, and xbox are the KEY_TITLE, and the third part is the KEY_BODY.
For some reason the ReceiveText class is having trouble pulling this information from the database, I really think it has something to do with when i Query the database, it asks for a columnindex, and i am putting a 0 as the parameter. Any ideas? Thanks again for all your help. It's a great learning process.
yeah, there doesn't seem to be a column with _id == 0
that is strange. when you defined it did you use "integer primary key autoincrement"? This should start at 0, I believe.. maybe you deleted your first entry at some point?
try it with 1 and see if that works.
Man, thanks so much for your help...it works! Here is how I did it from the ReceiveText class.
mDbHelper = new TextsDbAdapter(context);
mDbHelper.open();
getText = mDbHelper.fetchText(1);
message = getText.getString(2).toString();
getText is a Cursor type, and message is a String type.
I really appreciate the help, I understand a lot more now. My next step is to set the text to use without having to specify from the ReceiveText class...any suggestions? I was thinking adding another column in the database that would hold either a 1 or 0, and if it is selected, it updates the database and changes that field to a 1, then the ReceiveText class will query the database to return the field that has the 1...make sense? lol
Just to clear this up a bit for those still a little fuzzy:
Code:
Cursor c = db.query(TABLE_NAME3, new String[] {NAMESHORT, LAPTIME, LAPNUMBER}, null ,null, null, null, orderBy);
The column indexes are what you have in the "new String[]" area whether you have 1 or 50 items. So, NAMESHORT is index 0, LAPTIME is index 1 and LAPNUMPER is index 2. It's NOT the column number of where it is in the table
Just a personal preference of mine, but I code all this in the database methods and return what I need from there. Seeing hard-coded numbers in a program always bothers me. Instead of returning cursors I'll return a StringBuilder or ArrayList or whatever. Just sayn'
Hi,
Does anybody know how to pull the time from a server and use that time to update the devices clock?
I want to lock the Clock down on the device so the best way to ensure the time is correct is to sync it with a server.
I'm using VB.net.
Give this a spin.
It sets the get the UTC time, from http://www.timeapi.org/ , but have a look at the site to see what else it can do.
Your device should deal with your timezone offset from UTC automatically.
I used .NET Reflector to translate into VB from C#, hence the odd definition of some variables.
Code:
Public Structure SYSTEMTIME
Public wYear As UInt16
Public wMonth As UInt16
Public wDayOfWeek As UInt16
Public wDay As UInt16
Public wHour As UInt16
Public wMinute As UInt16
Public wSecond As UInt16
Public wMilliseconds As UInt16
End Structure
Declare Function GetSystemTime Lib "CoreDll.dll" _
(ByRef lpSystemTime As SYSTEMTIME) As UInt32
Declare Function SetSystemTime Lib "CoreDll.dll" _
(ByRef lpSystemTime As SYSTEMTIME) As UInt32
Private Shared Sub Main(ByVal args As String())
Dim Buffer As Byte() = New Byte(&H19 - 1) {}
Dim DateItems As String() = New String(8 - 1) {}
Dim Separators As Char() = New Char() { "-"c, "-"c, "T"c, ":"c, ":"c, "+"c, ":"c }
Dim Now As New SYSTEMTIME
Program.GetSystemTime((Now))
Dim ResponseStream As Stream = WebRequest.Create("http://www.timeapi.org/utc/now").GetResponse.GetResponseStream
ResponseStream.Read(Buffer, 0, &H19)
ResponseStream.Close
DateItems = Encoding.UTF8.GetString(Buffer, 0, &H19).Split(Separators)
Now.wYear = Convert.ToUInt16(DateItems(0))
Now.wMonth = Convert.ToUInt16(DateItems(1))
Now.wDay = Convert.ToUInt16(DateItems(2))
Now.wHour = Convert.ToUInt16(DateItems(3))
Now.wMinute = Convert.ToUInt16(DateItems(4))
Now.wSecond = Convert.ToUInt16(DateItems(5))
Now.wMilliseconds = 0
Program.SetSystemTime((Now))
End Sub
The original C# code is here. You will have to convert the C# 'using' statements to VB 'Imports'
Code:
using System;
using System.Net;
using System.Text;
using System.IO;
using System.Runtime.InteropServices;
namespace GetTime
{
class Program
{
[DllImport("coredll.dll")]
private extern static void GetSystemTime(ref SYSTEMTIME lpSystemTime);
[DllImport("coredll.dll")]
private extern static uint SetSystemTime(ref SYSTEMTIME lpSystemTime);
private struct SYSTEMTIME
{
public ushort wYear;
public ushort wMonth;
public ushort wDayOfWeek;
public ushort wDay;
public ushort wHour;
public ushort wMinute;
public ushort wSecond;
public ushort wMilliseconds;
}
static void Main(string[] args)
{
byte[] Buffer = new byte[25];
string DateString;
string[] DateItems = new string[8];
char[] Separators = new char[7] { '-', '-', 'T', ':', ':', '+', ':' };
SYSTEMTIME Now = new SYSTEMTIME();
GetSystemTime(ref Now);
Stream ResponseStream = WebRequest.Create("http://www.timeapi.org/utc/now").GetResponse().GetResponseStream();
ResponseStream.Read(Buffer, 0, 25);
ResponseStream.Close();
DateString = Encoding.UTF8.GetString(Buffer, 0, 25);
DateItems = DateString.Split(Separators);
Now.wYear = Convert.ToUInt16(DateItems[0]);
Now.wMonth = Convert.ToUInt16(DateItems[1]);
Now.wDay = Convert.ToUInt16(DateItems[2]);
Now.wHour = Convert.ToUInt16(DateItems[3]);
Now.wMinute = Convert.ToUInt16(DateItems[4]);
Now.wSecond = Convert.ToUInt16(DateItems[5]);
Now.wMilliseconds = 0;
SetSystemTime(ref Now);
}
}
}
Here's how it works: The call to the URL returns the date/time as a char buffer.
"2011-12-02T14:56:38+00:00" as an example.
After converting this to a string we convert it into an array of strings in DateItems[] as
2011
12
02
14
56
38
00
00
using Separators[] to split the fields apart.
These are then converted to ushort values in the time structure, before setting the time on the device with it.
Nice code stephj .
Cheers!!!
Thanks for that stephj, will give it a go.
i've tried this and i'm getting a :
The remote server returned an error: (407) Proxy Authentication Required.
any ideas?
I tried the above program on an emulated device connected to the net via its host PC's connection and it worked a treat.
To get through a proxy, you will need to add the following code.
Code:
Program.GetSystemTime((Now))
**************INSERT THIS ****************
Dim Proxy as new WebProxy("http://ProxyServer:80/",true)
proxy.Credentials = CredentialCache.DefaultCredentials
WebRequest.DefaultWebProxy = proxy
**************INSERT ENDS ****************
Dim ResponseStream As Stream = WebRequest.Create("http://www.timeapi.org/utc/now").GetResponse.GetResponseStream
Where the first parameter of the WebProxy constructor is the name of your proxy server, and the port it uses. Here at work, we can get away with just using our proxy server's internal network DNS name of "Internet:8080", to access the outside web through a Microsoft ISA Proxy/Firewall. Note in this case the proxy uses a different port number of 8080 as opposed to the default http port of 80. If yours is not 80 you will have to provide it. You may have to do some groundwork to track down the name of your proxy server, and the port it uses. I would start by looking at the proxy setup in Settings->Connections->'Set up my proxy server' for starters.
CredentialCache.DefaultCredentials, picks up your default login/credentials and passes them to the proxy server. If it works properly, you should go through it, seamlessly.
Good luck!
Hi steph,
i tweaked this slightly and set up a webreference in my program, i then pull the time down from that in the format of "2011-12-12T09:43:14", it then splits it.
The problem i am having is that sometimes it seems to add an hour to the time.
Any ideas?
What time zone is your device operating under?
Start->Settings->[System]->Clock & Alarms->[Time]
What's the zone, and is it Home or Visiting? - I'll see if I can duplicate it.
GMT London and is set as Home.
As a test I set the time on the device to: 01/06/1999 and time 01:00:00. When i run the program the first time i press my 'Update Time' button and it returns 12/12/11 and 12:53:04, so 1 hour ahead. If i press the button again I get the correct time.
I notice on your original post that the time returned had +00:00 on the end but you dont seem to use it when you break the string down, is this not required?
Thanks for the help, much appreciated
At least I can duplicate it, so that is a start. It only seems to throw the hour forward if the date has changed, which explains why the second call to it corrects the time.
If you just knock the time back a couple of hours, a single call of the program sets the correct time.
Interesting. I'll try and get to the bottom of it, might take a day or so, on and off.
Edit: Got it!
The 1st of June 1999 is in BST one hour in front of GMT/UTC. The first call changes the date and time using BST, leaving the time pushed forward one hour. The date is then set to today's date which is in GMT/UTC. The second call sets the time against the GMT Timezone which corrects the time.
Set the date time to 04:00 yesterday and it works fine.
I'll see if we can fix it a bit better. More later.........
Here's the cure: It's C#, I'll leave you to convert it to VB.
The secret is to set the time twice, but stall the thread for ten seconds inbetween. The device will sort itself out in the gap, as various time and date housekeeping tasks are triggered. The second SetTime(), will carry out the final fix of the time before the program finally ends.
This should also work in BST when changing from a GMT/UTC date, and should also work with all global time zones.
Add this:
Code:
using System.Threading;
SetSystemTime(ref Now);
Thread.Sleep(10000);
SetSystemTime(ref Now);
that's great steph, thanks again.
There is a minor problem with the previous code:- If the minute happens to roll over in the 10 seconds while the process is asleep, then the change of minute will be lost.
Here's a better solution. Create a DateTime object in which to store the returned date and time from the WebRequest().
Use it to set the system date/time, and then advance it forward ten seconds.
Set the date/time with it again, after the ten second sleep() has elapsed.
Seems to work O.K. Post bug reports to this thread, if you find it doesn't.
Code:
using System;
using System.Net;
using System.Text;
using System.Threading;
using System.IO;
using System.Runtime.InteropServices;
namespace GetTime
{
class Program
{
[DllImport("coredll.dll")]

private struct SYSTEMTIME
{
public ushort wYear;
public ushort wMonth;
public ushort wDayOfWeek;
public ushort wDay;
public ushort wHour;

}
static void Main(string[] args)
{
byte[] Buffer = new byte[25];
string DateString;

SYSTEMTIME Now = new SYSTEMTIME();
Stream ResponseStream = WebRequest.Create("http://www.timeapi.org/utc/now").GetResponse().GetResponseStream();
ResponseStream.Read(Buffer, 0, 25);
ResponseStream.Close();
DateString = Encoding.UTF8.GetString(Buffer, 0, 25);
DateItems = DateString.Split(Separators);
DateTime SaveTime = new DateTime(Convert.ToInt32(DateItems[0]),Convert.ToInt32(DateItems[1]),Convert.ToInt32(DateItems[2]),Convert.ToInt32(DateItems[3]),Convert.ToInt32(DateItems[4]),Convert.ToInt32(DateItems[5]));
Now.wYear = Convert.ToUInt16(SaveTime.Year);
Now.wMonth = Convert.ToUInt16(SaveTime.Month);
Now.wDay = Convert.ToUInt16(SaveTime.Day);
Now.wHour = Convert.ToUInt16(SaveTime.Hour);
Now.wMinute = Convert.ToUInt16(SaveTime.Minute);
Now.wSecond = Convert.ToUInt16(SaveTime.Second);
Now.wMilliseconds = 0;
SetSystemTime(ref Now);
SaveTime.AddSeconds(10);
Thread.Sleep(10000);
Now.wYear = Convert.ToUInt16(SaveTime.Year);
Now.wMonth = Convert.ToUInt16(SaveTime.Month);
Now.wDay = Convert.ToUInt16(SaveTime.Day);
Now.wHour = Convert.ToUInt16(SaveTime.Hour);
Now.wMinute = Convert.ToUInt16(SaveTime.Minute);
Now.wSecond = Convert.ToUInt16(SaveTime.Second);
SetSystemTime(ref Now);
}
}
}
C# .NET CF 2.0 WinMo 5.0 onwards executable is included in the zip file.
It is a console application, so don't expect anything much to happen until the 'hourglass' disappears.
If the first SetSystemTime() ends up changing the date across a Daylight Saving Boundary date, then, during the sleep() period, the device's housekeeping date/time/alarm services will probably retrigger any outstanding task and event reminders for 'today'.
P.S. GetSystemTime() can be dropped it is not required.
works like a charm steph, nice one. thanks.
@stephj, Thanks for the updated code .
Cheers!!!
Seem to be having a problem with this since UK has put the clocks forward an hour, every time I update using this code my device is adding an hour to the time.
The device is an M3 Mobile.
What are the settings on the Start-> Settings->Clock and Alarms->Time[Tab]
It should still have the Home radio button active and the time zone set to GMT London, Dublin. The mobile device should take care of daylight saving itself.
Is your M3 running WinMo 6.1 or 6.5? But I can't see it making much difference.
Works OK on a stock 6.1 Kaiser (Vodafone v1615)
Update: Also seems to work OK on the WM 6.5.3 Professional emulator.

Hi,
Does anybody know how to pull the time from a server and use that time to update the devices clock?
I want to lock the Clock down on the device so the best way to ensure the time is correct is to sync it with a server.
I'm using VB.net.

Well on my Kaisers (running either wm 6.1 or 6.5) I use SKTsync to sync my device clock to one of the NIST or SNTP servers. It's freeware and it does it all for you, all you do is run the app. It's soooo simple. I also run an app called CT Scheduler lite. I use it to automatically run SKTsync every night.
Hi,
I need to develop an android application using Eclipse and Netweaver Gateway plugin. When I run my code as a console application, it works fine. However, I'm unable to consume the OData services from the android application. I need to call an OData service, which is hosted on an ECC on an organization's server and display the details and whatever on the application screen (in text-fields or whatever). The "android.permission.INTERNET" is defined in the AndroidManifest.xml, already. See the code below: (Url & credentials have been omitted)
private void readExample() throws RestClientException, ParserException
{
String reqUri = "http://<some url>";
IServerConnectionParameters gateway = new ServerConnectionParameters("<host name>","<port>","<client>",false);
IAuthentication credentials = new UsernamePasswordCredentials("<username>","<password>");
IRestClient restClient = RestClientFactory.createInstance(gateway, credentials,Representation.ATOM);
IRestRequest request = new RestRequest(reqUri);
IRestResponse response = restClient.execute(request);
// Convert the response body XML into an ODataCollection object
ODataEntry collection = ODataUtil.parseODataEntry(response.getBody());
ODataProperty[] properties = collection.getProperties();
for (ODataProperty oDataProperty : properties)
{
Context context = getApplicationContext();
CharSequence text = oDataProperty.getValue();
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
}
This is the function which gets called on a button click event and for example here, the details should be fetched from the service and shown as toast messages. This block works very fine using command line, but I'm unable to consume this via android. The debugger gets stuck on the "IRestResponse response = restClient.execute(request);" line and after a while returns an error of "Connection ETIMEDOUT" and could not connect to the host.
I'm using two reference libraries : com.sap.nw.gateway.odata.client_2.6.400.201211111531.jar, odata4j-0.7.0-clientbundle.jar.
Could somebody please shed some light on this?? I'm deeply stuck and need this urgently!! :crying:
Nobody ready to help, guys?? :'( :'(

Hi,
Please use Gateway Productivity Accelerator (tools.hana.ondemand.com/#gateway) instead of the Netweaver Gateway plugin for Eclipse.
Also, in general, make sure you don't call to a very large amount of data in a single request, but rather use paging or other.
Regards
I'm a very accomplished coder when using interpreted languages, but this low-level memory management stuff is proving hard for me to get my head around.
I'm trying to work through the OpenGL ES sample code on the official developer site and I cannot understand why they create a ByteBuffer for the vertex list and then immediately turn around and create a FloatBuffer from the ByteBuffer. Why not just allocate and reference the FloatBuffer directly? Aren't there now two sets of data that basically refer to the same set of numbers? Here's the snippet to which I am directly referring (perhaps the reason lies elsewhere in the code, though?):
public class Triangle {
private FloatBuffer vertexBuffer;
// number of coordinates per vertex in this array
static final int COORDS_PER_VERTEX = 3;
static float triangleCoords[] = { // in counterclockwise order:
0.0f, 0.622008459f, 0.0f, // top
-0.5f, -0.311004243f, 0.0f, // bottom left
0.5f, -0.311004243f, 0.0f // bottom right
};
....
public Triangle() {
// initialize vertex byte buffer for shape coordinates
ByteBuffer bb = ByteBuffer.allocateDirect(
// (number of coordinate values * 4 bytes per float)
triangleCoords.length * 4);
// use the device hardware's native byte order
bb.order(ByteOrder.nativeOrder());
// create a floating point buffer from the ByteBuffer
vertexBuffer = bb.asFloatBuffer();
// add the coordinates to the FloatBuffer
vertexBuffer.put(triangleCoords);
// set the buffer to read the first coordinate
vertexBuffer.position(0);
}
}
It is basicallly due to the way Java uses data types. In the language of gods (C) we can just cast types and all is good.
What is happening there is a workaround basically.. machines have a word order (not sure if you have ever heard of the term back-words or byte ordering before) the ByteBuffer has a method which shuffles data to put it into the CPU byte order (ByteOrder.nativeOrder()) which can then be sent to the GPU.
Imagine the value 0xFFEE on an Intel CPU that would be stored as the 2 bytes 0xEE 0xFF or "backwards" if you will, it is called a Little endian CPU. An ARM CPU may store it is 0xFF 0xEE in memory as it is Big Endian
Since Java has it's own convention that it always uses, the ByteBuffer is there to provide a method to re-order it to whatever the CPU needs.
Hope my explanation is not more confusing! I am half-asleep and was just heading to bed :-S
